Dependent Articulation in the Global Pesticide Complex: Argentina's Agrochemical Industry After the Generics Market Revolution

Journal of Agrarian Change, EarlyView.
ABSTRACT Since the late 1990s, the pesticide industry has undergone a ‘generics revolution’ as the centre of production, and trade has shifted to the global South. China and India have become major producers, capturing Latin American markets from Northern multinationals. As a major pesticide user and a key node in global supply chains, Argentina offers

IL‐3 Modulates Microglia Polarization and Attenuates Neuroinflammation in Traumatic Brain Injury

Advanced Science, Volume 13, Issue 29, 22 May 2026.
IL‐3 recruits PRDX1 through IL‐3R to modulate the inflammatory response of microglia via the KEAP1‐NRF2‐HO‐1/NF‐κB pathway to attenuate neuroinflammation in traumatic brain injury. ABSTRACT Microglia play a crucial role in the progression of neuroinflammation following traumatic brain injury (TBI). Interleukin‐3 (IL‐3), a significant regulatory factor,

Nonlinear Asymmetric Blood Oxygenation Level Dependent Responses in Somatosensory Cortex

Human Brain Mapping, Volume 47, Issue 5, 1 April 2026.
BOLD responses to increments and decrements in intensity of vibrotactile stimulation were asymmetric. Negative BOLD effects (decrements in signal) were smaller in amplitude and slower to peak compared with positive BOLD responses to increases of intensity. BOLD responses were nonlinear for changes in stimulus duration and intensity.
